A study from The Ohio State University found that eating could reduce aggression between you and your spouse.

They found that the lower the blood sugar of a study participant, the lower the self-control. When a participant was angry with their spouse, they stuck pins in a voodoo doll, meant to represent their spouse. The lower the blood sugar, the more pins were inserted after the spouse was annoyed.

This isn't shockingly new information (we've all gotten a little "hangry" before), but good to know. While a snack doesn't guarantee a peaceful night, preventing low blood sugar could head off an argument, or at least relieve some of the aggression.
